湖北地方晒晾烟物理性状与其他质量评价指标的典型相关分析

以湖北恩施、宜昌、十堰、襄阳4个产区普查晾晒烟样本为材料，对烟叶外观质量指标和评吸指标进行量化鉴定，对烟叶物理性状和化学成分进行测定。通过使用典型相关分析方法分析烟叶物理性状与烟叶外观质量、化学成分和评吸指标间的典型相关性。结果表明，烟叶的物理性状与外观质量、化学成分和评吸指标之间均存在显著典型相关关系，烟叶物理性状与外观质量关系最密切；在烟叶评价质量组间关联上起主要作用的物理性状评价指标是单叶重、叶长及平衡含水率。

Canonical Correlation Analysis Between Physical Property and Other Quality Evaluating Indices of Tobacco Leaf

Canonical correlations of sensory quality, physical property, chemical components, and smoking quality were analyzed respectively using sun-cured tobacco samples from four tobacco growing areas of Hubei province. Results indicated that the evaluating indices between physical property and the other mentioned quality characters all showed significant canonical correlations. Relationship between physical property and sensory quality was the most significant. Physical property such as weight per leaf, leaf length and equilibrium moisture content played important roles between any two quality groups relationship.
